- Аннотация: Bimetallic FeCo and FeNi nanoparticles attract much attention due to their promising magnetic properties and a wide range of practical applications as recording and storage media, catalyticsystems in fuel cells, supercapacitors, lithium batteries, etc. In this paper, we propose an original approach to the preparation of FeCo- and FeNi/N-doped carbon nanocomposites by means of a coupledprocess of frontal polymerization and thermolysis of molecular co-crystallized acrylamide complexes.The phase composition, structure, and microstructure of the resulting nanocomposites are studiedusing XRD, IR spectroscopy, elemental and thermal analysis, and electron microscopy data. The mainmagnetic characteristics of the synthesized nanocomposites, including the field dependences andthe ZFC-FC curves peculiarities, are studied. It is shown that the obtained FeCo/N-C nanocomposites exhibit exchange bias behavior at low temperatures. In turn, FeNi/N-C nanocomposites areferromagnetically ordered.
